SOLOMON H. WOODS, OF BERLIN, ASSIGNOR FOR' ONE-HALF TORUSSELL S.GLADWIN, OF WEST MERIDEN, CONNECTICUT.

IMPROVED DIE POR MAKING SHEARS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may conce-rn:

Be it known that I, SOLOMON H. WOODS, of Berlin, count-y of Hartford,and State of Connecticut, have invented a new and useful Il nprovementin Dies for Forming Scissors and Shears;`aiid I do hereby declare thefollowing to be a full, clear, and exact description of thesaine,refcrence being' had to the accompanying drawings, and to theletters of reference marked thereon; said drawings constitute part ofthis specification, and represent, in

Figure 1, a face view of' 'the lower die; in

Figure 2, a face view ofthe upper die; in

Figure 3, a vertical cross-section of the two dies tO- gether, taken'through line X X, and showing the couvex surface of the portion of thedies which form the aperture in the centre ofthe circle or bow ofthehandle; in

Figure 4, a view ofthe blank, after it is forged,and before it hasbeenoperated on by the dies; and in Figure 5, -a-view of the same, afterpassing through the dies.

VSimilar letters of reference, when they occur in the separate figures,indicate like parts.

My invention relates to an improvement in dies for forming the one-halfof a pair of scissors or shears, (blade, shank, and bow,) from a blankformed by forging orotherwise approximating in shape to that of thefinished article.

The object of my invention is to provide a means of rapidly forging thisclass of cutlery, and to furnish an article of superior quality at aprice much below the present market value.

To enable others skilled in the art to make and use my improved dies, Iwill .proceed to describe their construction and operation.

A is the lower die, and is provided with an. indentation, a b, sunk `inits surface. The portion aof this indentation receives the blade of thearticle, and the other portion, b, receives one-half the handle, asshown in fig. 1.

B is t-he upper die, and is provided with an indentation, to exactlycorrespond with the portion marked b of the lower die. As the blade a isformed entirely upon one side, this portion ofthe upper die is left flatand smooth, as shown in fig. 2.

c is a small apertureor groove, for the purpose of admitting the rod towhich the article is attached, and upon which it is held until it isfinished. Before the metal is placed in the dies, it is drawn luider ahammer from a rod Or bar, to forni the blank as near as possible to therpropel' shape and size, and the said blank is left in form similar tothat shown in fig. 4. it is next placed in the dies, to be swaged orforged.

`The dies are set in operation, and as they strike the metal, thetendency is to spread and fill the indenta# tions. v

The portions C C of the dies which form the aperi ture in the bow orhandle maybe made slightly convex, as shown in fig. 3, in order tofacilitate the opere ation,and more eifectually spread the metal fromthe .solid lump. I do not, however, consider it absolutely necessary tomake the said portions in this form,` as a flat surface may be madeto'auswer the purpose.

The portions C C, whether flat or convex, operate first upoh the lump,or portion of the blank which forms theI handle, pressing '-it` outward,and forming the aperture.

After'thearticle has passed through the dies, there will be a thin filmof metal around the edges and across the bowor circle of the handle.This makes it necessary to pass' it through a set of trimming-dies,which cut away all the superfluous amount of metal, and leave thearticle ready for finishing.

lBoth of the two parts ofa pair of scissors can be made under one set ofdies, as the said part-sare eX- actly alike, and by placing the flatportions of the -bladcs together, they are brought into position forrivet-ing and use.

In shears, however, where the handles are of different dimensions, twosets of dies must be used-one set for each portion or half of the pair.

My improvement lis equally adapted to any size of scissors or shears.The size of the dies in each case must, of' course, be adapted to thesize of the article to be formed.

It may also be adapted to making the kind of shears styled slip-shears,which are used by mechanics for cutting tin or other sheet-metals. Forthis purpose, I make a set of dies which shall form simply the circle orbow ofthe handle u pon the bar, using the saine form as before describedfor pressing the metal ontward and into the proper indeutations in thedies, and forming the aperture in the centre of the said circle or bow.

I do not, broadly, claim a die for forming the blade of the scissors, assuch is not new; but

'hat I do claim as new and useful, and desire to secure by LettersPatent, is-

Ihe dies, constructed as shown and described, for forming scissors orshears from a wrought blank, substantially in the manner as hereinspecified.

SOLOMON H. WOODS.
